Rice is the most important staple crop in Nepal, playing a critical role in both the economy and food security. This study analyzes the trends in rice cultivation, production, imports, and exports from fiscal years 2011/2012 to 2021/2022 and also presents population data from the initial and final years. Over the study period, the area of rice cultivation declined by 0.81% annually, while the production grew by 1.5% per year, and the yield improved at a rate of 1.97% per year. Trend analysis indicated no significant changes in cultivation area or production, but a significant positive trend was observed in the yield. Rice import showed a significant annual increase of 5.61% in price value and 12.80% in quantity, while exports also grew by 1.95% in quantity and 2.39% in value. However, exports remain negligible compared to imports. Nepal's rice self-sufficiency ratio (SSR) has declined by 1.15% annually, falling from 92.72% in 2011/2012 to 82.01% in 2021/2022 while its import dependency ratio (IDR) has increased by 5.89% annually. These trends suggest that Nepal is becoming increasingly vulnerable in terms of rice food security. Population dynamics based on two census records revealed a notable 14% rise in the foreign population. This situation underscores the urgent need for policy interventions to address the decline in rice self-sufficiency, labor shortages, and growing import dependency, ensuring sustainable rice production and food security in Nepal.

DNA-decorated hapten (DDH)-based immunoassays have emerged, demonstrating supreme advantages in sensing applications because of their excellent sensitivity, specificity, and reliability. DDH combines both a recognition element (hapten) and a signal transduction element (DNA portion) with its highly programmable DNA structure enabling the trigger of signal transduction following a recognition event, thereby introducing a novel signal transduction mechanism to immunoassays. In this review, we provide a critical overview of recent research in the DDH-based immunoassays, which are designed to detect specific small molecules and antibodies.

Heat stress poses a significant challenge for maize production, especially during the spring when high temperatures disrupt cellular processes, impeding plant growth and development. The B-cell lymphoma-2 (Bcl-2) associated athanogene (BAG) gene family is known to be relatively conserved across various species. It plays a crucial role as molecular chaperone cofactors that are responsible for programmed cell death and tumorigenesis.

Rising atmospheric CO generally increases yield of indica rice, one of the two main Asian cultivated rice subspecies, more strongly than japonica rice, the other main subspecies. The molecular mechanisms driving this difference remain unclear, limiting the potential of future rice yield increases through breeding efforts. Here, we show that between-species variation in the DNR1 (DULL NITROGEN RESPONSE1) allele, a regulator of nitrate-use efficiency in rice plants, explains the divergent response to elevated atmospheric CO (eCO) conditions.

Skillful seasonal climate prediction is critical for food and water security over the world's heavily populated regions, such as in continental East Asia. Current models, however, face significant difficulties in predicting the summer mean rainfall anomaly over continental East Asia, and forecasting rainfall spatiotemporal evolution presents an even greater challenge. Here, we benefit from integrating the spatiotemporal evolution of rainfall to identify the most crucial patterns intrinsic to continental East-Asian rainfall anomalies.
